Internet Content Rating Association (ICRA)
Rating System

The Internet Content Rating Association seems to be a
semi-standard. It provides the most detailed information about your
page and has been adopted by Internet Exploder. It also makes an
attempt to encode whether adult content is portrayed in an educational
or artistic manner. It is, as you might guess, also the most complex
to configure. In addition, they provide some information on their web
site about their protocol. In the past they have refused to answer
questions about it saying that you should use their web form and not
do-it-yourself. However, they seem to have done a complete about face
and now have a lot of great documentation on their site.

Basically, their ratings are a list of codes, each two letters
followed by a space and the number 1. The starting letter inticates
the type and is (c)hat, (l)anguage, (n)udity, (v)iolience, and
(o)ther-topics. The second letter, for each type, describes the
specific classification. For instance la means that the page
uses "Explicit sexual language" while va implies "Sexual
violence / rape". After each two letter code comes a space and the
number 1. I could find no documentation about the 1.

Notice that you don't set a level of nudity or other types but
rather you list each of the items which are represented on your page.
Also, if you show "Explicit sexual acts" (nf) but in an "Artistic"
context (nr) you would list both entries: (nf 1 nr 1)
